Patented Ldan. 14, 1939 UNITED HABEY A. MUNDORFF, JB., OF WILMINGTUN, DELAWARE MOLD FOB. FROZEN CARBONATED CONFECTONS Application filed August 27, 1929. Serial No. 388,773.

the present invention is to provide means of this character which will hold the carboniol acid gas within-the li uid and prevent its u 4A Ifurther object is to provide means for this purpose including a mold, a cap adapted to close -over the mold and-have gas-tight engagement therewith, a valve in the cap whereby the carbonated li uid ma be forced into the cap and so into t e mol of the receptacle, and means for clamping the cap in air-ti ht engagement with the mold.

A, lrther object is to provide a mechanism u of this character which may be arranged to permit the freezin of a plurality of confectins simultaneous y. v l

Other objects will appear in the course of the following description. 1

-My invention is illustrated in the accompanying drawings, whereinz-,

Figure 1 's a. vertical sectional v1ew through a mold constructed in accordance with my invention; Y

Figure 2 is a perspective view of the rod clamping means detached.

Referring to these drawings, designates a plate which may be of brass and have mj' the receptacle 111s filled to the proper exdesired length and width, the width depen ing upon the size of the molds carried b this brass late and the length upon the mo ds so carried. Each brass plate is formed with a plurality of openings depending from which are the cop er-tubes or receptacles 11 w1th1n which the Iliquid to be frozen 1s dlsposed. These receptacles are, of course, open at the top, but closed at the bottom. Immediately around the openinfr for the receptacle 1n the plate 10, the plate 1s formed with a countersink at 12 wherein is disposed a gasket 13 of tains carbonio acid gas, one of the objects of l escape in the form of bu bles from the liquidr rubber or other suitable material. The brass plate 10 at its ends or at any desired points 1s provlded with the upwardly extending stud bolts 14. Coacting with the plate 10 is a confront- 55 'ing' plate 15 likewise preferably made of brass, though I do not wish to be limited to this, having holes 16 at its ends throu h which the stud bolts 14 pass, the stud bo ts being provided with thumb nuts. 60 These thumb nuts 17 engagel the stud bolts so as to hold the plate 15 down against the plate 10.v

Mountedwithin the plate 10 lare a plurality of heads orcaps 18, there being a cap or head for each of the receptacles 11. The lower end of each cap or head is flanged at 194 to t within the countersunk opening 12 and bear against the gasket 13. Within each head adjacent the lowerend thereof is a '410 spring clip designated 2O having opposed resilient jaws which is adapted to carry a Y. preferably wooden rod or.stick 21 andv support this stick in the receptacle in centered relation thereto with the upper end of this'y 76 stick projectin above the mouth of the receptacle 11. ach cap 18 at its upper end carried a fil-ling tube 22 which extends down into the head and extends upward above the head. Disposed within the tube is a valve 8o stem guide or lspider 23 through which the valve stem 24 passes. This stem at-its lower end, has the head 25 and abovefthis head the gasket 26 or washer which'ts against the lower end of the'tube 22. When this valve 85 stem is depressed,.liquid can pass throu h the spider 23 and out ofthe lower uend of t e tube 22 and into the receptacle 11. When tent the valve formed by the parts 25 and 26 9 0 is allowed to close under the action of the spring 27 which surrounds the valve stem.

It will be seen that the mold receptacles 11 are entirely closed so as to retain the car- ,bonic acid gas within the'liquid until the 95 fections including the 1i uid is frozen, the upper plate 15 is removed from the lower late.

The molds will then e dipped into warm Water which Will permit the removal of the finished product. The finished products are then lifted out of theseveral mold receptacles 11 b means of the sticks 21. It will be understoo of course, that the molds may be dipped into warm water before the plate 15 is removed from its engagement with the plate 10 if desired. The spring clamps 20 are U-shaped as shown in Figure 2 and have sufficient tension to keep the clamping means constantly closed. These spring clamps keep the stick in position until the carbonated liquid has been converted to a frozen solid.

-These s ring clamps slip over and release their ho d upon the stick when the upper section is being removed because of the fact that the carbonated liquid and stick is frozen solid and clings to the molds or receptacles 11. The clamps are fastened von the inside of the fillin caps 18 by means of screws I28. It will e understoodl that by the term sticks I refer to wooden sticks or sticks of other material. These sticks are preferably fiatsided but'may have any other cross-sectional form.

It will be seen that my structure may have any desired length and thus act to sup ort and fill any number of tubes 11 and that tliese tubes may be frzen as a unit and removed from the refrigerating medium as a unit and dipped into Warm water as a unit. The device is very simple and has been found particularly effective. Where a carbonated liquid is to be frozen, unless provision is made for preventing the escape of carbonic acid gas, 1t is impossible to freeze thisliquid Without it becoming vapid and lifeless and losing the life given to it by the included carbonio acid gas.

Obviously may be modications might be made without departing from the spirit of the invention as defined inthe appended claims. Y

1. A device for freezin carbonated cona plate aving a freezing receptacle exten ing therefrom, a second plate adapted to be held against the firstnamed platev and having a capformed to have air-tight. engagement with the first named plate and with the receptacle, means within the cap for supporting and centering a stick within the freezing receptacle, and a valve permitting the introduction of carbonated liquid into said cap but closable against the escape of gas therefrom.

2. In a device of the character described, a freezing receptacle acting as a mold, a cap adapted to be brought into air-tight engagement with the freezing receptacle, and having means Within the cap for supporting and centering a stick within the freezing receptacle, the cap having means permitting the inlet of liquid into the receptacle, but preventing the outlet of gas therefrom.

3. A device of the character described, comprising a plate, a plurality of freezing receptacles constituting molds and depending from the plate, a confronting plate, means for forcing said plates into engagement with each other, the confronting plate having a plurality of caps, equal in nu'mber to the freezing receptacles, the first named plate having' countersunk openings around the openings of the freezing receptacle and provided With a gasket and each capy having airtight engagement with the corresponding gasket, and means disposed Within each ca for supporting and centering a stick`vv`it'h'i'n the freezing receptacle, and means permitting the introduction of liquid into the cap but preventing the the escape of gas therefrom.
